M8-1.25×50mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 316不鏽鋼 (100個/包)

The hex socket drive bit right in without stripping, and the 316 stainless finish is clean and uniform across all 100 pieces. These feel solid enough for my jig builds, and the partial threading gives good grip where it matters.

The 316 stainless steel is noticeably tougher than the 304 I've used before, and the hex socket drive fit my wrench perfectly without any stripping. I installed a dozen of these on a new tooling fixture and they held torque exactly as expected.

The hex socket drive on these is crisp, no stripping even after torquing them down hard on a jig. The 316 stainless finish looks clean and should hold up better than the cheap zinc ones I’ve used. Exactly the thread pitch I needed for a precise assembly.
